  • the reconfiguring of OTT connection 1350 may include message format, retransmission settings, preferred routing etc.; the reconfiguring need not affect base station 1320 , and it may be unknown or imperceptible to base station 1320 .
  • measurements may involve proprietary UE signaling facilitating host computer 1310 's measurements of throughput, propagation times, latency and the like.
  • the measurements may be implemented in that software 1311 and 1331 causes messages to be transmitted, in particular empty or ‘dummy’ messages, using OTT connection 1350 while it monitors propagation times, errors etc.
